Thermal or hydrothermal treatments of boron-containing pentasil-type zeolites, as well as acid-leaching procedures, lead to the partial or full removal of the framework boron atoms from the material. Resulting from this removal, the boron-stimulated

Die Ergebnisse von 29Si- und 23Na-MAS-NMR-Untersuchungen an vier Modifikationen des synthetischen Na2Si2O5 zeigen, das sich die α-, β- und δ-Modifikationen eindeutig durch die Parameter ihrer NMR-Spektren voneinander unterscheiden lassen. Die Unte
